If you do lots
of experimenting with whip type antennas, here is an idea for
a unique, simple and inexpensive method for mounting
them!

The Simpson Strong Tie "T"
(aka hurricane connector) runs less than $5 at Home Depot or Lowes and
already comes with two 1/2" holes predrilled. Just bend (or use as
is for horizontal dipole) and install CB 3/8" connectors and go!

The V beam mount (shown in the second picture below), is
bolted to a 1/2" EMT mast for mobile use.

Use as a horizontal dipole
or bend 90 degrees for a
horizontal V beam! Just bolt bottom of "T" to your mast.
For heavier antennas, use two "T's" back-to-back bolted or welded
together.

On left of photo above shows bending for vertical or
horizontal dipole. On right it is shown bent for V type antennas and
mounted on short mast.
